  1. PIP- Booster RF Tuner and Cavity Refurbishment 3/7/12 M. Slabaugh

  2. Refurbishment • One cycle of cavity and tuner refurbishment nearly complete October 2011 - March 2012 • Included: • Transport to MI-60 (1-2 days) • Setup and testing in MI-60 cave (2-3 months) • Disassemble (1-2 days) • Cavity vacuum leak repair (1 week) • Tuner prep (2 spare, one good) (3 weeks) • Reassemble with new cooling lines (1 week) • Testing and trouble shooting (1-2 months) • Estimated return-to-duty week of March 19??

  3. Refurbishment- Challenges • Safe handling- tuners weigh ~ 625lbs. • Cone cooling and repair • Fit-up and tolerances to cavity • Training/manpower

  4. Refurbishment • Handling • Have fixtures being made in the machine shop • FESS formalizing requirements for beam hoist in the room • Developing procedures and checklists

  5. Refurbishment Cone • Single largest challenge to tuner mechanical refurbishment- needed for additional cooling • To refurbish a cone: Strip  Burn  Grit blast  Braze Clean/grind Tape Spray  Epoxy/assembly  Clean  test  tin plate

  6. Refurbishment Cone • Developing process to refurbish the cones without stripping • Remove old tube epoxy new tube  test  tin plate • Have shown it is theoretically possible to repair damaged fingers • If we can make this work, will simply repair cones already in the tuners

  7. Refurbishment Training and manpower • Adequate effort at present, beneficial for another technician in near term • TD is willing to provide effort • Two contract technicians • Great work ethic, eager to learn • Quickly developing needed skills • Could lose them anytime
